What is EN steel grade S690QL material machinability

S355N is a kind of weldable fine grain structural steel grade under EN10025-3 standard. It is often delivered in normalized or normalized rolled condition. There are various shapes available for EN steel grade S690QL material, S355N: steel plates, strip and steel sections. When producing this steel S355N plates, dimension, tolerances on thickness, width, length and shape shall be in accordance with the requirement given in the order by reference to the relevant documents according to EN10025-1 standard.

Our company specializes in the production of steel plates, steel coil, steel sections, welded pipes and seamless pipes products, sales of GB, ASME, ASTM, JIS, DIN, EN, API and other standards and specifications of steel EN steel grade S690QL material and deep-processed products, facing the domestic and foreign markets, welcome to call for inquiries. It is a modern high-tech professional enterprise integrating scientific research, production and sales.

EN10025-6 S460QL structural steel plates are European standard low alloy high strength steel materials. EN steel grade S690QL material, S460QL steel plates are mainly used for building and engineering structures, such as plant structure, body steel frame components of bulldozers, loaders etc. all kinds of construction machinery, bridges, ships and so on.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the EN steel grade S690QL material principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
